The approach to the study of subgrades and subbases the nationwide variation in soil types. The major problems of concern in the design of rigid pavements are discussed. Soil classification and its limitations are discussed; the bases for the most popular systems are described briefly. The major properties that should be ascertained before a material is used as an integral member of the pavement system are considered and methods of test are referenced to standard specifications. Subbases are discussed from the standpoint of use in rigid pavement systems as well as their requirements for satisfactory service.
